Definitions

  • the invention relates to a ski or a snowboard in the form of a board-type gliding device, of the type defined in claim 1 .
  • Patent specification DE 24 17 156 A1 describes a ski comprising at least two sliding strips disposed adjacent to one another. These gliding strips are connected to one another by fixing means to enable a relative movement of the two gliding strips, at least in their middle portion, in the vertical direction with respect to their gliding surface. This produces a multiple, in particular twofold edge support, which is intended to permit a better grip to prevent lateral skidding.
  • the mechanical coupling between the two gliding strips requires complex mechanisms, which means that a design of this type is not especially suitable in practical terms.
  • Patent specification DE 41 30 110 A1 describes a ski with a three-dimensionally profiled top face.
  • the ski is formed by a one-piece composite body made up of a plurality of layers or plies adhesively joined to one another.
  • this one-piece ski comprises a top belt, a bottom belt, side faces and a core surrounded by these elements.
  • the top belt is made up of several layers.
  • An intermediate layer is disposed between a layer of the top belt and a superficial layer or the core, which has a different thickness and/or width in the longitudinal direction.
  • This intermediate layer may incorporate a support and/or damping element or may be provided in the form of one.
  • the ski binding is attached by fixing means, such as screws for example, to the one-part ski, for example via the intermediate layer and/or the core.
  • the binding fixing screws extend into the core element of the ski and terminate short of the bottom face of the ski.
  • the top belt construction adhered or integrally formed on the top face of the ski body incorporating varying stepped width and/or thickness dimensions therefore affects the stiffness curve of the one-piece, multi-layered ski in steps.
  • a ski of this type is also of a relatively stiff design in the region of the binding mounting zone, especially when a shoe is inserted in the ski binding.
  • Patent specification WO 00/62877 A1 describes an alpine ski with a body made up of several elements, which has a running surface on its bottom face and a region on its top face for attaching a binding.
  • This structure also has at least one top belt element which is primarily subjected to compression and at least one bottom belt element which is subjected to tension.
  • the top belt element has a flat, upwardly cambered arch in the middle region of the ski, which extends in the longitudinal direction of the ski and spans the bottom belt element. The arch of the top belt element is therefore able to flex in the direction towards the bottom belt element depending on the load emanating from the binding.
  • the top belt element is supported so that the shift in the ends of the top belt element caused by the flexing of the arch increases the amount of support afforded by the end regions of the ski.
  • This design enables a more uniform distribution of surface pressure across the running surface of the ski to be obtained.
  • the highest possible support length of the ski edges can also be achieved, which slightly improves stability when travelling in a straight line as well as the reaction of the alpine ski to control pulses of the skier.
  • the travel dynamics or the enjoyment which can be achieved with this design is still not satisfactory for many skiers.
  • Patent specification WO 2004/045727 A1 describes an alpine ski with a ski body, which has a running surface on its bottom face and, on a top face, facing away from its running surface, at least one top belt element extending in the longitudinal direction of the ski body which absorbs tension and compression forces.
  • This top belt element is supported on the ski body by its ends, and a wave-shaped support structure is provided on the top face of the ski body, on which the top belt element is mounted.
  • the wave-shaped support structure is formed by a longitudinally extending flat component, which is bent at an angle with respect to the running surface about spaced apart, essentially parallel axes extending transversely to the longitudinal direction of the ski. This is intended to produce good running properties and good controllability of the alpine ski.
  • Patent specification DE 198 36 515 A1 filed by this applicant discloses a distribution mechanism for transmitting loads and/or forces on a sports device, as well as a sports device incorporating same.
  • the distribution mechanism comprises a support element for a coupling mechanism designed to retain the sports shoe of a user.
  • This plate-type support element for the coupling mechanism can be connected to a board-type sports device, in particular a ski, at its end regions by means of articulated joint arrangements. At least one end region of the plate-type support element is connected to an intermediate support so that it can pivot via an articulated joint arrangement, which in turn is supported on the board-type sports device and/or on another support holder by means of two articulated joint arrangements spaced at a distance apart from one another in the longitudinal direction towards the support element.
  • this support construction comprising a plate-type support element for the coupling mechanism and several intermediate supports and articulated joint arrangements disposed between the top face of the sports device and the support element, the forces to be transmitted from the support element to the sports device, in particular emanating from the middle region, are distributed as uniformly as possible.
  • the disadvantage of this approach is that the arcuate intermediate support and the respective linking articulated joint arrangements increase the complexity of the structure, thereby making the overall weight of such a sports device relatively high.
  • the standing height for the foot of the user is relatively high compared with the running or gliding surface of the sports device, and the various articulated joint arrangements and longitudinal guides do not guarantee the desired ability to turn and slide longitudinally between the respective components under adverse usage conditions to a sufficiently high degree.
  • the invention on the basis of a board-type gliding device incorporating the characterizing features defined in claim 1 .
  • the essential factor is that the ski proposed by the invention or the snowboard proposed by the invention offers significant advantages over board-type gliding devices known from the prior art in terms of its travel properties.
  • a ski or snowboard is proposed, the vibration behaviour and hence also travel behaviour of which is significantly influenced by the plate-type force-transmitting element, so that the claimed winter sports devices above all produce an excellent edge-gripping capacity or tracking capacity, which is extremely important in terms of accurate turning, especially when initiating a turn.
  • the specified plate-type force-transmitting element imparts to the gliding board body exactly the desired stability or strength to enable cut or so-called “carved” turns to be made in the snow as safely and controllably as possible.
  • the claimed board-type gliding device therefore gives the user the requisite, sufficiently high stability and imparts a high controllability or guiding stability to the gliding device as a whole.
  • the gliding board body in contact with the ground underneath unexpectedly flexes or virtually kinks, causing the board-type gliding device to suddenly assume a behaviour that is difficult to control.
  • a harmonic or uniform turning action can be generated within a relatively high load region of the gliding board body, which also increases personal safety when using the gliding board body proposed by the invention.
  • the specified plate-type force-transmitting element therefore stabilises the gliding board modified as claimed, resulting in good controllability and a conducive guiding behaviour.
  • the plate-type force-transmitting element suppresses or reduces high-frequency vibrations in the vertical direction with respect to the running surface facing, at least in an end portion of the gliding board body, such as primarily occur when travelling at speed over rough slopes, especially when turning, which is an advantage.
  • Another advantage is the fact that the forces applied by the user or the control movements initiated by the user via the interconnected force-transmitting element can be introduced into exactly those portions of the gliding board body in which the plate-type force-transmitting element is able to produce the most pronounced or best effect with respect to the gliding board body.
  • An embodiment defined in claim 4 is also of advantage because it offers a particularly robust, elastically flexible connecting means between the plate-type force-transmitting element and the gliding board body.
  • the elastomeric damping element is reliably retained and mounted as a result and is therefore able to withstand relatively high loads without any risk of the damping element tearing or shearing off.
  • the damping element is disposed in the plate-type force-transmitting element and not the gliding board body. This offers a simple way of producing different characteristics by fitting different force-transmitting elements and damping elements to a standard gliding board body.
  • a specific type of gliding board body can be selectively fitted with the plate-type force-transmitting element or not, which offers economic advantages for producers and/or relatively low costs for users of the gliding board bodies.
  • the advantage of an embodiment defined in claim 5 is that a connection can be obtained between the plate-type force-transmitting element and the gliding board body which is particularly resistant to breaking and tearing out.
  • the production complexity involved in manufacturing the board-type gliding device can be kept to a minimum because a relatively short time is needed to assemble the connection between the plate-type force-transmitting element and the gliding board body.
  • the board-type gliding devices produced as a result will remain functionally reliable for a long time and their properties will remain largely constant even after long-term or intensive use. In particular, it is possible to prevent fixing screws from gradually working loose due to widening of the material more easily, thereby providing a firm seating for the fixing screws.
  • damping elements with a relatively large surface area can be used, which have optimized damping characteristics and elasticity.
  • the mechanical strain of such damping elements can be kept to a minimum due to their relatively wide extension.
  • the damping element is also easily and reliably prevented from falling out or being torn out of the plate-type force-transmitting element.
  • the stabilization function and simultaneously the damping function of the plate-type force-transmitting element can be transmitted to appropriately extensive longitudinal portions of the gliding board body.
  • the multi-functional action, i.e. the damping and stabilization action, of the plate-type force-transmitting element is imparted in full to the gliding board body without the need for any structurally complex features.
  • This construction results in a bigger screwing-in depth and a longer active thread length for the screw-type fixing means of the binding mechanism, which results in a high degree of resistance to the screw-type fixing means tearing out.
  • the thickness or vertical height of the plate-type force-transmitting element can therefore be selected so that it is relatively short, which means that the overall height of the gliding device, in particular the standing height of the user of the gliding device from the ground underneath, can also be kept low, even though the gliding board body has a plate-type force-transmitting element mounted on the top of it.
  • the screw-type fixing means do not penetrate the top face of the gliding board body lying underneath, but a sufficient resistance to tearing out is obtained even though the screw-type fixing means are not anchored in the gliding board body.
  • the advantage offered by the features defined in claim 11 is that, in spite of opting for a relatively slim plate height for the plate-type force-transmitting element, a high tearing resistance is obtained for the screw means used to assemble a binding mechanism. Nevertheless, the plate-type force-transmitting element with the binding mechanism affixed to it is still able to slide as freely as possible in the longitudinal direction relative to the gliding board body disposed underneath it, so that tensions between said components caused by flexing are avoided as far as possible during flexing.
  • the advantage of the embodiment defined in claim 12 is that a guide mechanism extending in the longitudinal direction of the gliding device is provided, which increases trans-verse stability between the plate-type force-transmitting element and the gliding board body. In particular, this enables strong forces to be transmitted between the gliding board body and the plate-type force-transmitting element without the occurrence of shifting movements and without incurring an increased risk of damage to said components. Due to the partially positive coupling between the plate-type force-transmitting element and the gliding board body, the extra connecting elements which are needed between said components, in particular fixing screws, may be of a lower rating and/or their number may be reduced and/or their positioning can be optimized.
  • Another advantage of this embodiment resides in the fact that, due to the elongate, positive coupling, a high resistance to twisting is achieved between the plate-type force-transmitting element and the gliding board body by reference to an axis extending perpendicular to the running surface facing.
  • the advantage of the features defined in claim 14 is that a pronounced, positive coupling can be established between the force-transmitting element and the gliding board body without having to drastically modify the standard structural design of a gliding board body, in particular an alpine ski, in order to produce the requisite load-bearing capacity and make the distal end portions of the gliding board body advantageously lightweight.
  • virtually standard construction methods that have been tried and tested in practical applications can be used to make the gliding device proposed by the invention incorporating the gliding board body and the force-transmitting element mounted or supported on it as inexpensively as possible and in a proven way.
  • the gliding board body has an ideal bending characteristic curve as far as possible because its bending behaviour is influenced by the plate-type force-transmitting element as little as possible, especially in the region of the mounting zone for a binding mechanism, which means that a bending characteristic curve can be achieved which is as harmonious and uniform as possible. Due to the features defined in claim 15 , a packet of board-type or plate-type elements is obtained, as it were, which permits relative movements between the bottom face of the plate-type force-transmitting element and the top face of the gliding board body in the longitudinal direction when the overall construction is subjected to an arcuate, elastic flexing.
  • the advantage of the embodiment defined in claim 16 is that a particularly stable and strong connection can be obtained between the plate-type force-transmitting element and the binding mechanism or one of its components, even if the plate-type force-transmitting element has a relatively short plate height or plate thickness within the mounting zone for the binding mechanism.
  • the plate height or plate thickness of the plate-type force-transmitting element can be kept relatively short but a sufficiently strong connection strength or connection stability can still be guaranteed between the plate-type force-transmitting element and the binding mechanism.
  • the overall height comprising the plate thickness of the plate-type force-transmitting element and the thickness or height of the gliding board body to be kept relatively short so as to avoid unfavourably high standing heights for the user from the ground underneath, in particular the ski slope, in certain instances.
  • the advantage of the embodiment defined in claim 17 is that the end user has the impression of having a mounting for the binding mechanism and its guide tracks on the plate-type force-transmitting element which has no screws.
  • the structural combination of the binding mechanism or its guide tracks and the plate-type force-transmitting element gives the visual appearance of being cast in one piece as a result, which firstly results in an attractive visual appearance.
  • the blind bores extending from the bottom to the top through the binding mechanism or its guide rails prevent water from being able to collect in the seating bores for the connecting screws, which can generally lead to the formation of rust and/or cause damage if water that has penetrated the seating bores freezes and loosens the correct seating of a screw or screws or damages parts of the binding mechanism.
  • the connection quality between the plate-type force-transmitting element and the binding mechanism or its components is also improved.
  • the advantage offered by the embodiment defined in claim 18 is that the standing height of the user of the board-type gliding device from the ground underneath, in particular from the ski slope, is not significantly increased due to the extra plate-type force-transmitting element mounted on the top face of the gliding board body.
  • the component unit comprising the plate-type force-transmitting element and the gliding board body within the binding mounting portion is of a relatively low design. Consequently, it is possible to cater for the individual wishes or requirements of different users as regards the standing height above the ground, in particular above a ski slope, more easily and in a simple manner because respectively adapted binding mechanisms and co-operating interconnected guide rails or binding plates make it relatively easy to adapt to respective wishes or requirements within a relatively broad range of adaptation.
  • the user can choose between a relatively low standing height and a relatively high standing height from the ground underneath. Furthermore, without any difficulty, allowance can be made above all for the rules which apply to competitive sports with regard to the maximum permissible standing height of the user from the ground underneath or from the bottom face of the gliding device. This also applies in the case of standard binding mechanisms with a predefined structural height mounted on the top face of the plate-type force-transmitting element.
  • the embodiment defined in claim 19 is of advantage because a so-called sandwich compound element is produced, which acts as a plate-type force-transmitting element.
  • this is based on a design construction which has been tried and tested for many years in the production of board-type gliding devices, in particular winter sports devices.
  • a particularly stable plate-type force-transmitting element which best meets current requirements is obtained, the manufacturing costs of which can be kept to a minimum because the equipment and materials conventionally used by producers of the gliding device can also continue to be used or employed to produce the plate-type force-transmitting element.
  • plate-type force-transmitting elements can be produced which offer a good ratio between strength and lightness of weight.
  • the plate-type force-transmitting element is ideally able to assume the function for imparting some of the requisite static overall strength, which means that the gliding board body lying underneath can be made to correspondingly smaller dimensions in terms of its structure, without causing problems with regard to robustness or every day use of the gliding device as a whole.
  • the features defined in claim 20 result in a plate-type force-transmitting element which advantageously meets current technical requirements.
  • a force-transmitting element is able to withstand prevailing stresses without any difficulty and the requisite forces can be transmitted and absorbed with a high degree of reliability.
  • Such a plate-type force-transmitting element is also relatively lightweight but still of a sufficiently stable design.
  • Another major advantage resides in the fact that the components needed to produce the structure of conventional skis or snowboards can also be used for the plate-type force-transmitting element, thereby making production as cost-effective as possible.
  • the decorative methods or decorative options which are used on conventional skis and snowboards and have proved themselves in practical application can also be used for the plate-type force-transmitting element.
  • the appearance of the plate-type force-transmitting element can be ideally combined with the appearance of the gliding board body disposed underneath it. This firstly results in a good and harmonious appearance and also simplifies technical production, resulting in better economy, amongst other things.
  • the plate-type force-transmitting element affords a relatively high stability or torsional strength in spite of having a relatively low height.
  • a relatively lightweight and at the same time relatively stable plate-type force-transmitting element can be produced especially if the width contour of the plate-type force-transmitting element more or less conforms to the width contour of the gliding board body, and the width dimensions of the plate-type force-transmitting element essentially correspond to the width dimensions of the gliding board body or are only negligibly smaller.
  • the features defined in claim 23 produce a longitudinal compensation that is as obstacle-free as possible between the plate-type force-transmitting element and the gliding board body, which more easily results in improved bending behaviour, in particular a bending characteristic curve of the overall construction that is as ideal as possible. Furthermore, such longitudinal compensating movements can be converted as effectively as possible into springing or damping movements with respect to the gliding board body. This also prevents the appearance of abrasion or scratches so that the attractive appearance of the ski or snowboard in the region of the zones of relative movement between the force-transmitting element and the gliding board body are preserved for a long time.

Only the most essential components are illustrated as examples in these drawings. Also in the individual drawings, only the most essential part-components are illustrated, in particular those of the gliding board base body and the plate-type force-transmitting element.
  • the board-type gliding device 1 is preferably a ski 2 or a snowboard.
  • a ski 2 is used in pairs, whereas the user of a snowboard is supported with both feet on a single board body.
  • the gliding device 1 has a least one binding mechanism 3 , which may be designed as a safety-release binding or a binding which provides a coupling without flexing.
  • the board-type gliding device 1 is based on a sandwich or monocoque structure.
  • a plurality of layers are joined to one another by adhesive and together constitute the one-piece gliding device body.
  • these layers form at least one top belt 4 which imparts strength, at least one bottom belt 5 which imparts strength and at least one core 6 disposed in between.
  • the top belt 4 and/or the bottom belt 5 may be made from at least one plastic layer and/or metal layer and/or fibre layer and/or epoxy resin layer and such like.
  • the core 6 may be made from wood and/or from foamed plastics. The core 6 therefore essentially spaces the top belt 4 apart from the bottom belt 5 of the gliding device 1 , both of which are impart strength.
  • the top face 7 i.e. the top external face of the gliding device 1
  • the bottom face 9 i.e. the bottom surface of the gliding device 1
  • the top layer 8 may also extend across at least certain regions of the side faces of the board-type gliding device 1 and form a box-type structure in conjunction with the running surface facing 10 , as may be seen in particular from the diagram in cross section shown in FIG. 4 .
  • the side edges of the running surface facing 10 are preferably bounded by control edges 11 , 12 , preferably made from steel, to permit an exact as possible and largely slip-free guiding action of the gliding device 1 .
  • the control edges 11 , 12 which are key to controlling and guiding the gliding device 1 , are rigidly joined to the structure, in particular to the running sole or bottom belt 5 of the gliding device 1 .
  • the control edges 11 , 12 are preferably positively and non-positively fixed in the gliding device structure in a manner known per se.
  • the running surface facing 10 is permanently joined to the gliding device structure, in particular to its bottom belt 5 , across its entire top flat face directed towards the core 6 .
  • the running surface facing 10 is preferably adhered to the surrounding components of the gliding device 1 by its entire surface.
  • the running surface facing 10 or bottom face 9 of the gliding device 1 is of a flat or straight design as viewed in cross-section through the binding mounting portion, as illustrated in FIG. 4 , when the gliding device 1 is in its original state not placed under load, in which case the gliding device 1 in the initial state free of load has an essentially flat bottom face 9 and running sole.
  • the structure described above is decisive in determining the strength, in particular the bending behaviour and torsional stiffness, of the board-type gliding device 1 .
  • These strength values are predefined or predetermined by the materials used and layer thicknesses and by the methods used for joining purposes.
  • the essential factor is that at least one plate-type force-transmitting element 13 is supported on the top face 7 of the actual gliding board body, at least within part-portions, and transmits force or load.
  • a contour or lateral shape of the gliding device 1 defined by its design results in a varying width 14 of the gliding device 1 and/or the plate-type force-transmitting element 13 in the longitudinal direction of the gliding device 1 , as may best be seen from FIGS.
  • the plate-type force-transmitting element 13 in addition to the actual gliding board body—FIG. 2 —the plate-type force-transmitting element 13 also has a so-called shaping, specifically provided in the form of arcuate indentations at the longitudinal side edges of the plate-type force-transmitting element 13 , imparting a substantially concave contour to the plate-shaped force-transmitting element 13 as seen in plan view.
  • the shaping or the side shape of the plate-type force-transmitting element 13 therefore more or less conforms to or is essentially the same shape as the shaping or side shape of the gliding board body, as illustrated by way of example in FIG. 3 .
  • the width 47 of the plate-type force-transmitting element 13 is preferably selected so that it is smaller at all the longitudinal portions than the corresponding width 14 of the gliding board body within the same or congruent longitudinal portions.
  • the plate-type force-transmitting element 13 does not therefore project beyond the longitudinal side edges of the gliding board body.
  • the gliding device 1 offers high personal safety and a high degree of safety against injury.
  • the plate-type force-transmitting element 13 preferably extends from the binding mounting portion in the direction towards the rear end portion and in the direction towards the front end portion of the gliding board body, as may best be seen from the diagrams shown in FIGS. 1 and 3 . This makes it possible to vary the travel behaviour of the gliding board body significantly by means of the plate-type force-transmitting element 13 and impart a pronounced influence to it.
  • the distal ends of the force-transmitting element 13 are able to move relative to the top face 7 of the gliding board body in its longitudinal direction so that relative movements are possible between the force-transmitting element 13 and the gliding board body when the co-operating gliding device 1 is subjected to flexing or bending.
  • the top layer 8 of the gliding board body is preferably provided in the form of a plastic layer, which is decorated on at least one side.
  • This top layer 8 forms the predominant portion of the top face 7 of the gliding board body.
  • This top layer 8 preferably also lines at least part-portions of the external longitudinal side walls, as may best be seen from FIGS. 3 , 4 .
  • the plate-type force-transmitting element 13 is supported within its longitudinal extension, in at least part-portions, on the top face 7 of the gliding board body and transmits loads or forces.

It is of advantage if the force-transmitting element 13 extends across approximately 51% to approximately 96%, preferably across 66% to 86%, of the projected length of the gliding board body. By projected length is meant the length of the gliding board body as viewed from above.
  • the longitudinal extension of the plate-type force-transmitting element 13 is essentially limited by the fact that the plate-type force-transmitting element 13 should not extend into the upwardly curved shovel portion or end portion of the gliding board body so that it does not pose an obstacle to the relative movements between the ends of the plate-type force-transmitting element 13 and the gliding board body when this leaf spring-type packet comprising force-transmitting element 13 and gliding board body is subjected to a downward flexing or a lifting of the binding mounting portion or middle portions relative to the end portions.
  • the upwardly curved shovel portion of the gliding board body would constitute a block with respect to the terminal end of the plate-type force-transmitting element 13 or inhibiting forces would occur if the plate-type force-transmitting element 13 were to extend in a straight line or also in an upwardly cambered arrangement into the shovel portion of the gliding board body.
  • the plate-type force-transmitting element 13 extends across approximately two thirds to approximately nine tenths, for example across approximately three quarters, of the length of the gliding board body between the binding mounting centre point 15 and the respective end of the gliding board body or by reference to the total length of the gliding board body, a good ratio can be achieved between weight optimization and the stability or functionality of the gliding device 1 as a whole.
  • the plate-type force-transmitting element 13 acts as a support for transmitting load, in particular for mounting a binding mechanism 3 for a user's shoe.
  • a binding mechanism 3 is attached to the top face of the plate-type force-transmitting element 13 in a known manner.
  • the binding mechanism 3 may comprise a front jaw and a heel jaw, which are connected to the top face of the plate-type force-transmitting element 13 either directly or via an interconnected guide rail arrangement.

  • an adequate connection can be achieved between the force-transmitting element 13 and the binding mechanism 3 by means of this least one screw means 16 , 17 , preventing any tearing out.
  • the binding mechanism 3 is therefore supported with respect to the actual gliding board body with the plate-type force-transmitting element 13 connected in between.
  • the board-type gliding board body has its biggest thickness or width, as may be seen from FIG. 4 , thereby enabling a sufficiently strong mutual positive connection or engagement between the plate-type force-transmitting element 13 and the gliding board body, as illustrated by way of example in FIG. 4 .
  • the positively acting coupling means 19 , 20 is designed so that it permits relative movements between the force-transmitting element 13 and the gliding board body in the longitudinal direction of the gliding board body to compensate for longitudinal movements when the gliding board body and the plate-type force-transmitting element 13 are subjected to flexing, as would be the case when travelling over mounds, for example.
  • the positively acting coupling means 19 , 20 is designed to prevent relative movements between the force-transmitting element 13 and the gliding board body in the transverse direction with respect to the longitudinal extension and essentially parallel with the running surface facing 10 of the gliding board body as far as possible and affords increased resistance against any such shifting tendencies.
  • the at least one positively acting coupling means 19 , 20 permits relative movements between the plate-type force-transmitting element 13 and the gliding board body in the longitudinal direction of the gliding board body but prevents lateral shifting movements between the plate-type force-transmitting element 13 and the top face 7 of the gliding board body, as may clearly be seen by comparing FIGS. 1 and 4 .
  • This partially positively acting connection between the plate-type force-transmitting elements 13 and the gliding board body is therefore conducive to achieving as direct and delay-free a transmission of forces as possible between the force-transmitting element 13 and the gliding board body without the bending behaviour of the gliding board body being impaired by the plate-type force-transmitting element 13 .
  • the positively acting coupling means 19 , 20 is preferably designed with at least one stud-type or strip-type projection 21 , 22 on the bottom face 18 of the force-transmitting element 13 , which locates in a co-operating or complementary recess 23 , 24 in the top face 7 of the gliding board body and improves the mechanical coupling between said components.
  • the at least one but preferably two rows of stud-type or strip-type projections 21 , 22 on the bottom face 18 of the force-transmitting element 13 may also serve as a means of accommodating the front portion, in particular the tip portion 25 , of the screw means 16 , 17 for attaching the binding mechanism 3 to the plate-type force-transmitting element 13 .

  • this provides a relatively strong anchoring for the screw means 16 , 17 , preventing them from being torn out, and hence a particularly reliable and strong enough connection for the binding mechanism 3 and its layered arrangement to the plate-type force-transmitting element 13 to prevent it from being torn out.
  • the screw means 16 , 17 described above, the tip portions 25 of which extend into the material of the projections 21 , 22 , may also be provided as a means of securing guide elements, in particular guide rails or so-called binding plates for the jaw bodies of the binding mechanism 3 .
  • the essential aspect is that a relatively long anchoring or screwing length exists within the plate-type force-transmitting element 13 if the at least one projection 21 , 22 on the bottom face 18 of the force-transmitting element 13 is also advantageously used to increase the screwing-in depth for the screw means 16 , 17 , as may best be seen from FIG. 4 .
  • a profile height 26 of the at least one, preferably strip-type projection 21 , 22 becomes smaller starting from the binding mounting centre point 15 in the direction towards the rear and front end of the gliding board body continuously or in steps and preferably diminishes to zero.

  • the at least one recess 23 , 24 in the top face 7 of the gliding board body extends across approximately one third of the length of the gliding board body, and it should be pointed out that this portion will also depend on the respective length of the different gliding board bodies, i.e. whether the gliding board body is relatively long or relatively short. Accordingly, the oppositely lying end portions of the recesses 23 , 24 expediently merge flat or flush into the top face 7 of the gliding board body, as may be seen in particular from the perspective diagram shown in FIG. 1 .
  • the gliding board body therefore has the groove-type recesses 23 , 24 in its middle portion in which the gliding board body has a sufficient or relatively large depth or thickness.
  • the recesses 23 , 24 will therefore have the biggest receiving depth 27 , whereas the receiving depth 27 becomes continuously shorter towards the end portions of the gliding board body or reduces in steps and finally preferably diminishes to zero.

  • Screw means may also be provided in the immediate vicinity of the binding mechanism 3 , which connect the plate-type force-transmitting element 13 to the gliding board body lying underneath via elongate holes oriented parallel with the longitudinal direction of the force-transmitting element 13 so that different bending or chord lengths between said components can be compensated as far as possible unhindered.
